Conventional Ball Valve Design |
'Dissolution' Ball Valve Design |
The forces required to maintain the tightness are stressing all components - even the ball and seats. The operating torque is thus very high.
|
The forces needed to maintain the tightness between ball seat and valve body are only directed onto the corresponding graphite seal rings. The ball is only spring-loaded, which ensure a low, defined, minimum pressure off the balls on the ball seat. A smooth operation is the consequence.
